Problems solved by technology

[0009] In addition, in the restriction control method based on ON / OFF of the control channel, if the base station stops the control channel for restriction, the service area constituted by the base station does not exist. Therefore, while the base station stops transmission of the control channel, the When a new base station constituting a service area starts to operate at the same position as the service area originally constituted by the base station, there is a problem that interference is detected in the base station when the restriction is to be lifted, and in order to utilize the original service area It takes more than the stipulated time, or may not be able to use the original service area

Embodiment 1

[0035] figure 1 It is a block diagram showing the transmission and reception functional configuration of the base station of the mobile wireless communication system according to the first embodiment of the present invention. The base station 1 of the mobile wireless communication system shown in this figure has a control channel transmission and reception control unit 2, a control time slice combination / separation unit 3, a wireless modem unit 4, a traffic concentration detection unit 5, and a unique word pattern memory. Part 6, sending and receiving antenna 7.

[0036] Next, the general function of each of these components will be described. exist figure 1Among them, the control channel transmission and reception control unit 2 controls the transmission and reception of the control channel of the base station 1 . The control time slice combination / separation unit 3 combines the physical time slices for control according to the control from the control channel transmissi...

Embodiment 2

[0051] Figure 7 It is a block diagram showing the configuration of the transmission and reception functions of the mobile device in the mobile radio communication system according to the second embodiment of the present invention. The mobile device 8 shown in this figure is configured to further include a unique word pattern storage unit 16 capable of storing a plurality of predetermined unique word patterns. In addition, in other configurations, the configurations are the same as or equivalent to those of the mobile device 8 in the first embodiment, and these parts are denoted by the same symbols.

[0052] In the mobile radio communication system of Embodiment 1 above, the restriction control is performed on all mobile units during the restriction control, but in the mobile radio communication system of this embodiment, for the mobile devices divided into a plurality of groups, Restriction control is performed for each of the plurality of groups.

[0053] Figure 8 It is ...

Embodiment 3

[0063] In the above-mentioned embodiments 1 and 2, there is no special regulation for the bit structure of the non-standard unique word pattern. On the other hand, this embodiment shows a structure suitable for a bit pattern which is a non-standard pattern. In addition, an example in which the system configuration that is the premise of this example is selected is shown.

[0064] Figure 12 is a signal space diagram showing the arrangement of symbols on the phase plane of the π / 4-shift QPSK modulation system used in the simple mobile phone system (PHS), Figure 13 is a diagram showing the differential encoding rule of π / 4 shift QPSK.

[0065] In the signal space diagram, since the distance from the origin to the symbol corresponds to the amplitude of the modulated signal, when the movement between symbols passes near the origin, the amplitude fluctuation of the modulated signal becomes large. If the amplitude fluctuation range becomes large, an amplifier capable of handling...

Abstract

A wireless access inhibition can be ensured even for such mobile units that ignore regulation signals for regulating wireless accesses. There are included a control channel transmission / reception control part for controlling control channel transmissions and receptions; a control slot construction / separation part for performing control physical slot constructions and separations based on a control of the control channel transmission / reception control part; a traffic concentration determination part for monitoring the traffic status of wireless lines to determine whether the traffic is concentrated; and a unique word pattern storage part for storing a unique word pattern to be designated when the control channel transmission / reception control part sends a control physical slot constructionrequest to the control slot construction / separation part. When regulating the accesses from mobile units to the base station based on the monitor result of the traffic concentration determination part, the control slot construction / separation part changes the unique word pattern to be set in the control physical slot to a pattern other than the patterns as specified in standards.

Description

technical field [0001] The present invention relates to a mobile wireless communication system constituting a base station, a mobile device, and a mobile wireless communication system restriction control method for restricting the use of a wireless line between the base station and the mobile device. Background technique [0002] Recently, various mobile wireless communication systems are operated by a plurality of communication carriers, and the number of users thereof is further increasing. On the user side, the frequency of use is increasing due to its convenience, and communication traffic is also rapidly increasing due to the diversification of usage forms such as mail and content services. [0003] Not limited to mobile wireless communication systems, in communication systems, if calls and traffic are concentrated in a specific area, the communication path will be in a congested state, making it difficult to communicate. In particular, due to the mobility of mobile de...
